NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 760,887, dated May 24, 1904.

Application filed November 3,1903.

To all whom it may concern.-

Be it known that I, EMIL C. LUKS, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Non-Refillable Bqttles;v and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in non-refillable bottles, the object being to pro' duce a bottle which after being emptied of its contents cannot be refilled.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view of a portion of a bottle, showing my improve.- ments; and Fig. 2 is a detail view of one of the rod guide-disks.

The numeral 1 indicates the neck of a bottle, and it is formed with a circular internal projection or shelf 2 near its lower end. This I shelf has a partially tapered or countersunk central opening 3, in which rests a weighted valve 4:, adapted to close said opening. This Weight or valve is formed with a central vertical rod 5, a portion of which extends above it, and a portion 5 depends from the under side thereof. To the upper end of this rod is secured a valve 6. annular ring 7, of cork or other suitable material, is located in the bottle-neck some distance above the weighted valve 4, and the valve 6 seats against the upper sidev thereof. A circular'disk 8 is secured to the under side of this ring, 7 and also a like ring to the under side of the shelf 2. These disks may, if preferred, be formed integral with the ring and shelf and act as guides for the rod 5.

cated by the numeral 9, to permit the free flow'of liquid through them. When these disks are formed separate from the rings,they are secured thereto preferably by means of small projections or prongs 10, bent from the body thereof and forced into the ring. A

They are perforated, as indi- Serial No. 179,691. (No model.)

coiled spring 11 surrounds the rod 5 and bears against the under side of the disk 8 and the upper side of the weighted valve 4, tending to keep both valves 4 and 6 closed.

In the bottle-neck near its mouth is located a suitable screen 12 of comparatively fine mesh, allowing liquid to flow freely through it, but not permitting the insertion of any instrument for interfering with the other parts. The mouth of the bottle is free to allow the insertion of the usual cork or stopper 13.

When the bottle is tilted, the valve 4: will fall away from its seat and being of suflicient weight will compress the spring 11, raising the valve 6 from its seat and permit a free flow of the liquid from the bottle.

The screen 12 will permit the liquid to flow freely through it; but it will tend to retain all dross and settlings that may be contained therein. V

The device may be formed directly in the bottle-neck, as shown, or it may be formed in a tube and then inserted into the neck of the bottle.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

- A non-refillable bottle having a circular internal shelf 2 With' a central opening, formed near-the lower end of the-bottleneck,a weighted valve 4-. having a tapered bottom adapted to close the opening in said shelf, a vertical rod 5 carried by said Weighted valve, a valve 6 mounted on the top of said rod, a coiled spring surrounding said rod, a circular ring bearing against the inner Wall of the bottleneck against the upper side of which saidvalve 6 seats, perforated disks 8 secured to the under side of said ring and shelf, a screen near the mouth of the bottle and a stopper 13, all sub-
